— | The Basic Learning Kit is a multifunctional expansion board that is designed for beginners learning the Arduino platform, but can also be used to create various projects that require a large variety of sensors and modules. Almost all additional Arduino modules can be connected to this board. The following components are located on the expansion board: 4 LEDs, a seven-segment four-digit display, an active buzzer, a trimmer resistor, 4 buttons (one of them is for resetting the Arduino board system, and the remaining three can be used to navigate through the device menu, change the threshold value, activate sensors etc.). An active buzzer is designed to reproduce sound signals. The buzzer is active as there is a built-in generator in its case. When current is applied to the buzzer, its relay coil excites a magnetic field. Under the action of a magnetic field, the relay contacts open. After opening the contacts, the current in the circuit disappears and the magnetic field disappears, after which the springs return to their original position. The process is then repeated as long as current is applied to the circuit. Due to the vibrations of the armature, air vibrations appear, which reproduce the sound of the buzzer. An active buzzer can be used as a siren to notify you of any activity. The 10 kΩ trimmer is a passive electronic component for fine tuning device parameters. With this resistor, you can change the volume of the buzzer, the sensitivity of the sensors, the brightness of the LEDs, LED display, etc. Also on the expansion board there are contacts for connecting additional external modules and sensors.

— | The analog thermistor module KY-013 is designed to determine the ambient air temperature. The module board consists of: SMD resistor with a nominal value of 10 kOhm and a temperature sensor KY-013. This module can be used in air cooling system, home alarm system and other projects. The KY-013 thermistor and resistor are assembled according to the resistor voltage divider circuit. When the temperature changes, the resistance of the temperature sensor changes, which leads to changes in the voltage at the data output. After that, the controller measures the received voltage and, using the logarithmic conversion formula, converts the voltage into temperature. Also with the help of the module it is possible to determine the surface temperature. To do this, it is necessary to mechanically press the sensor to the surface using fasteners, through the connectors on the board, and apply heat-conducting paste between the surface and the thermistor.

— | The sensor is used to control the air temperature in the room when building temperature controllers, automation of heating systems, automation of ventilation systems. The comparator detects the temperature exceeding the set threshold and issues a logic signal to the digital output D0 and at the same time allows you to evaluate the temperature value at the analog output A0. Due to the output at which a signal is generated with a logical one or zero level, which indicates whether or not the temperature threshold has been exceeded, it is convenient to use the temperature sensor module in circuits based on discrete elements without using a microcontroller. For example, if the output of the KY-028 module is connected to the gate of a field-effect transistor of sufficient power to turn on a fan operating from 12 V. According to this scheme, an automatic cooling device for an electronic device can be assembled. The receiving element of the sensor is a thermistor. It is connected to the input of the LM393 comparator chip. With the help of a tuning resistor, the comparator threshold is adjusted. When exceeding the temperature of the set threshold at the output D0 will be a high voltage level. If the temperature is below the set threshold, then output D0 will go low.

— | The active buzzer module is designed to emit sound signals. It can be used in simple projects where it is necessary to use an audible signal when motion is detected, etc. The module board is designed based on the YL-44 active buzzer and auxiliary components for the correct operation of the module. The buzzer is active as there is a built-in generator in its housing. When current is applied to the buzzer, its relay coil excites a magnetic field. Under the action of a magnetic field, the relay contacts open. After opening the contacts, the current in the circuit disappears and the magnetic field disappears, after which the springs return to their original position. The process is then repeated as long as current is applied to the circuit. Due to the vibrations of the armature, air vibrations appear, which reproduce the sound of the buzzer. There are 3 pins on the active buzzer module board: VCC: supply voltage 3.3 - 5V I/O: control signal GND: ground Power is supplied from an external power source, Arduino platform or other microcontroller device. The module supply voltage range is from 3.3 V to 5 V. When working with the active buzzer module in the Arduino IDE, you can use the "TONE" library.

— | The ACS712 sensor allows you to measure current up to 5 A and transfer measurements to the microcontroller of the Arduino board. The module can be used to measure and control current in such devices: charger, overload protection board, power supply, etc. The work of the module is to use the Hall effect. This effect occurs as a result of the influence of the Lorentz force on electrons, which changes the movement of electrons in the presence of a magnetic field. As a result, an EMF appears due to the flow of current at the edges of the plate. The current sensor module is designed based on the ACS712T chip in the SOIC package. Inside the chip are a Hall sensor and a copper conductor through which current passes, creating a magnetic field. On different sides of the plate, the density of free particles is different, which causes a potential difference, which is recorded by the Hall sensor. The main feature of the microcircuit is the large thickness of the conductor, which allows the passage of current many times greater than the permissible value of the microcircuit. The sensor is connected to the Arduino platform through 3 pins. The VCC and GND pins are used to supply power, and the OUT pin is used to transmit the fixed values of the sensor or receive data from the microcontroller device, and connects to the analog port of the Arduino board. Terminal J1 is used to connect the measured power supply. External source terminals are clamped with copper bolts for accurate current readings.
